GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 314) = 127170
GCD(810, 314) = ( 810 x 314 ) / 127170
= 810 / 314
= 810
Step2:
LCM(2, 438) = 438
GCD(2, 438) = ( 2 x 438 ) / 438
= 2 / 438
= 2
Step3:
LCM(2, 388) = 388
GCD(2, 388) = ( 2 x 388 ) / 388
= 2 / 388
= 2
So, Greatest Common Divisor of 810, 314, 438, 388 is 2
